     These data come from the first systematic panel study on voting,
     conducted by Lazarsfeld and his associates in Erie County, Ohio in
     1940 (Lazersfeld et al, 1948; Lazarsfeld, 1972, Wiggins, 1973,
     Hagenaars, 1993). The data are presented in Table 6.3 and refer to
     the variables A - _Party preference at time 1_ - August 1940 (1.
     Republican 2. Democrat), B - _Presidential Candidate preference at
     time 1_ (1. for Willkie 2. against Willkie), C - _Party preference
     at time 2_ - October 1940, and D - _Presidential Candidate
     preference at time 2_. Wendell Willkie was the (defeated) 1940
     Republican presidential candidate running against the Democrat
     Franklin D. Roosevelt.
